BIO328H5 Lecture Notes - Lecture 4: Sexual Selection, Statistical Power, Coevolution
Document Summary
Jan/11/2012: co-evolution between parasites and control the behaviour of the host. Parasite may induce symptoms in the host: look for evidence to rule out hypothesis. Statistical power of experiments decline in terms of the scientific truth and wears off. Regreassion to the mean: scientific outliers, basic more comprehensive sensible analysis. Science is not a very good way of finding out truths: turn to well tested hypothesis instead. Social interactions between members of the same species. Sexual dimorphism: peacock and feathers, body size, structures like elephant whales, webs in spider, weaponary such as in stag beetles (females don"t have them, male parasitic fish in female, hair important to detect bed bugs. Darwin come up wit hthe idea to explain sexual dimorphism: sexual selection in competition for passing on genes. Also alfred wallace: but darwin rushed the abstract to printers. Diff penis sizes in lizards: a genital display when implanted in female. Biologists accept darwins idea that males evolve weaponry.
